SPECIFICATION forming part of Letters Patent No. 770,507, datedSeptember 20, 1904.

Application filed May 10, 1904. Serial No- 207,Z29. (No model.)

To rtZZ whom it may concern:

Be it known that 1, ANDREW E. SABLE, a citizen of the United States,residing at Nanticoke, in the county of Luzerne and State ofPennsylvania, have invented a new and useful Grain-Separator, of whichthe following is a specification.

This invention relates to grain-separators.

The object of the invention is in a rapid and thoroughly practicalmanner to effect separation of the grain from any containedimpurities-such as pebbles, lumps of dirt, pieces of wood, and thelikeand also to separate therefrom any metal, such as nails or pieces ofwire, which by entering the mill would cause damage to its machinery.

With the above and other objects in view, as will appear as the natureof the invention is better understood, the same consists in the novelconstruction and combination of parts of a grain-separator, as will behereinafter fully described and claimed.

In the accompanying drawings, forminga part of this specification, andin which like characters of reference indicate corresponding parts,there is illustrated one form of embodiment of the invention capable ofcarrying the same into practical operation, it being understood that theelements therein exhibited may be varied or changed as to shape,proportion, and exact manner of assemblage without departing fromthespirit thereof.

In the drawings, Figure 1 is a View in perspective viewed from the frontside of the machine. Fig. 2 is a view in longitudinal section. Fig. 3 1sa view in transverse section.

forming a screen to effect cleaning of the grain, the screen beingprovided at its ends with downturned flanges 4?, which are suitablysecured to the end plates 5 and 6of the separating-chamber, thus to holdthe screen in proper operative position.

The plates 5 and 6 have converging upper and lower sides provided Withinward-projecting flanges 7 and 8 and parallel ends 9 and 10, the objectof having the upper and lower sides disposed at an angle to each otherbeing to furnish a hoppershaped mouth to receive the grain and aninclined discharge chute for directing the flow of grain from themachine. The rear wall 11 of the trough is plain throughout and issecured to the ends 9 of the separatingchamber; but the front wall 12 isprovided with an outward-extending flange 13, against which are adaptedto bear the crests of a series of vertically-disposed horseshoe-magnets14, the limbs of which pass through perforations in a flange 15,projecting from the trough. These magnets are closely disposed andoperate in a positive manner to catch and retain any metallic particlesthat might escape through the screen along withthe grain. Beneath thescreen and secured to the flange 8 of the end plates is adeflector-plate 17 constituting the bottom of the separating-chamber,provided throughout the greater portion of its length with an opening18, and arranged on the under side of the deflector-plate are a pair ofguides 19, in which works a slide 20, provided at its outer end with ahandhold 21, the object of the slide being normally to close the opening18, but when removed or withdrawn from under the opening to permit ofdetachment from the magnets of any caught metallic substances. To therear upper part of the chamber is hinged a door 22, provided withdownturned flanges'23, which are adapted to engage with the outer sidesof the end plates, the door being held in an inclined position by theinclined upper sides of the end plates, thus forming a mouth or opening24 at the front of the device, through which grain is fed to theseparating-screen.

Carried by the end plate 5 is a rectangular spout or extension 25,which, in effect, constitutes a continuation of the trough and isdesigned to project through an opening 26 in one side of the upper endof the offtake 2. This latter is a rectangular structure and has itsupper end closed by a plate 27, which may be rigid therewith orremovable therefrom, as desired.

In the operation of the device the grain is 1 bottom, and a slideconstituting a portion of supplied through the mouth or chute to thetrough and thence passes down the deflectingplate between the magnets tothe place of deposit. The foreign matter separated from the grain-suchas sticks, stones. or the lilrepass through the offtake, it beingunderstood that the separating-chamber is slightly longitudinallyinclined to cause the feed of refuse to the said offtake. Any finemetallic substances such as bits of wire, nails, or the likethat escapethrough the separating-screen are caught and retained by the magnets14:, from which from time to time they are removed through the opening18 by withdrawing the slide 20.

The apparatus of this invention is exceedingly simple of construction,will be found thoroughly efficient and durable in use for the purposesdesigned, and owing to the manner in which the parts are constructed andassembled repairs may readily be effected when necessary.

Having thus described the invention, What is claimed is 1. In agrain-separator, a separating-chamber having an inclined bottom andscreen, and a series of magnets inset from the front of the chamber andresting upon the said bottom.

2. In a grain-separator, a separating-chamber, provided With an inclinedbottom and with a screen, a series of magnets inset from the front ofthe chamber and resting upon the the bottom and disposed'beneath themagnets.

23. In a grain-separator, a separating-chamber, a trough disposedtherein and having an outturned flange, and an open-work bottomconstituting a screen, a flange projecting from the lower portion of thetrough and provided with a series of openings, and horseshoe-magnetshaving their limbs arranged Within the openings and their crestsdisposed beneath the first-named flange.

L. In a grain-separator, a separating-chamher, a trough arranged thereinand provided with an open-Work bottom forming a screen, and a series ofmagnets inset from the front of the chamber and held in position on aprojection from the trough.

5. In a grain-separator, an ofltake-chute having an opening near itsupper end, a separating-chamber having a trough arranged therein andprovided with an extension engaging the opening in the ofitake-chute andwith a screen constituting its bottom, and a series of magnets insetfrom the front of the chamber and held in place by the trough.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two Witnesses. I

ANDREW E. SABLE.
